(NEED ASAP!) how does crossing over during meiosis allow for genetic variablity?

Answers

Answer 1
Homologous chromosomes pair, then the chromosomes cross over in certain points. Then the Chromosomes break up and then pair again which results in different genes since they traded. Which is the result of genetic variability.

Show different life cycle patterns with the help of near labelled diagram

Answers

Answer:

The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.

This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).

Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

A.
What do humans need to keep mice healthy as pets?
B.
Was there a change in the genetic traits of the mice?
C.
Were the genes of the mice inherited from their parents?
D.
Was there a change in the environment where the mice live?

Answers

Answer:

D if there is a change in environment that would favor black fur you could assume that natural selection caused the fur to change

Explanation:

The question which should be asked to determine whether the population changes are a result of natural selection or artificial selection is that was there a change in the environment where the mice live? Thus, the correct option is D.


What is Natural selection?

Natural selection is the process through which the populations of different living organisms adapt and change with respect to their surrounding environment. Individuals in a population are naturally variable, it means that they are all different in some way or the other. This variation in the population means that some individuals have traits which are better suited to the surrounding environment than others.

If a mouse population changes its color from white to black over many generations, then the question which should be asked is "Was there a change in the environment where the mice live?"

Therefore, the correct option is D.
